DAPD10-40 Piloted 3-Way Spool, External Vent
V
DESCRIPTION
A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for three-way circuits requiring remote pilot actuation.
OPERATION
In neutral (unpiloted),the DAPD10-40 allows flow passage from 3 to 2 bidirectionally, while fl ow is blocked at .V is a spring chamber vent-to-atmosphere, which is internally O-ring sealed from the cartridge fl ow paths.On remote pilot signal at 1 , the valve shifts to open from 3 to 4 ,while blocking flow at 2 .Because of the vented spring chamber, the cartridge may be fully pressurized at any port without affecting required pilot pressure.
FEATURES
● Hardened spool and cage for long life.
● Industry common cavity.

Note:This valve is designed with a dynamic oil-to-atmosphere seal in the vent section. Ambient conditions will cause this vent seal to degrade which will reduce the valve’s cycle life. If this could cause a problem, we suggest that a non-vented model be selected. Consult factory for assistance.
